Implements Kendo.Mvc.UI.ISchedulerEvent

I have Implemented Kendo.Mvc.UI.ISchedulerEvent and added a few more custom properties of my own to the class.
I have also set editable to using a template id, Editable(Function(e) e.TemplateId("ScheduleEditTemplate")

Now if I access the custom properties of the class like ${CustomProperty}, it works fine, but if I access any of the implemented properties like ${Description} I get an error such as "Title is undefined"
any ideas, thanks
